Manual reset
I installed my new filter but my app still says I need to install new filter. It requires a manual reset and I was unable to do that.

Original filter
I have not installed it yet as the wildfire smoke hasn’t reached here yet. My original filter still has some life so I will use (and love,love,love) it until I need to install the new one.
